Merge tag 'drm-fixes-2021-07-30' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "Regular drm fixes pull, seems about the right size, lots of small
  fixes across the board, mostly amdgpu, but msm and i915 are in there
  along with panel and ttm.

  amdgpu:
   - Fix resource leak in an error path
   - Avoid stack contents exposure in error path
   - pmops check fix for S0ix vs S3
   - DCN 2.1 display fixes
   - DCN 2.0 display fix
   - Backlight control fix for laptops with HDR panels
   - Maintainers updates

  i915:
   - Fix vbt port mask
   - Fix around reading the right DSC disable fuse in display_ver 10
   - Split display version 9 and 10 in intel_setup_outputs

  msm:
   - iommu fault display fix
   - misc dp compliance fixes
   - dpu reg sizing fix

  panel:
   - Fix bpc for ytc700tlag_05_201c

  ttm:
   - debugfs init fixes"
